Following up with my previous post.
Installed new starter, cleaned ALL connections, tested the coils, was able to get sparks! I have a new fuel pump/filter on order, have flushed the lines with fresh 50:1 fuel. Motor will turn over very well, spark on all 4 cylinders, it just won't fire up.
Steps done thus far...
1. New Starter
2. Cleaned ALL connections from battery - starter, and everything in between
3. New fuel filter/pump on order
4. Flushed All lines with fresh fuel (50:1)
5. Sprayed the carbs with cleaner (I know they will ultimately need to be rebuilt, but trying to get it firing off / somewhat running before sending it for carbs and new water pump, etc.
6. New plugs
7. Removed the Black/yellow wire (same result either way)
Any other thoughts? When I sprayed the carbs, it would attempt to fire...so I am thinking fuel system...I am currently running it off of an AUX tank, have also sprayed fuel mixture into the carbs directly via a spray bottle (trying anything at this point)...
Also, on the 1975 model, where is the pee hole? I've had Mercs in the past, but first time with an Evinrude...just want to make sure of where to be looking, once I get it running...

they did not have water tell-tales back then.
Occasionally you will see mist or at high speeds, water flow, out of the exhaust relief holes.
Did the motor attempt to fire up when you sprayed into the carb openings? That is not a recommended procedure due to safety concerns.
